Belcw s rocketwheel d there is mounted upon siiaft d a second sprocket-wheel d?, which transmits motion by chain e to a sprocket 4o wheel f This wheel is rotatably mounted upon a vertically-movable rod f, which is in vertical alinernent with shaft l). Chain c and s rocket-wheels l1* d correspond in size to c ain e and sprocket-wheels 7" d, so that sprocket-wheels b2 and f will rotate with the same speed'and their relative positions will always remain the same.

and may be raised and lowered, so as to bring he can-body into or out of engagement with the seaining means hereinafter described.

For operating ro f a hand-lever g, inluf enced by a spring g', is provided,.\\hich is connected by .a link g2 to.-a .collarv g3, loosely fitted upon the rod. Upon collar g3 are supported a-pai icushvons g, that -bear against acollarf, secured to rodf. By depressing handlefgzrodf and platform f2 will -be raised, while :uponreleasing the handle .therod-,and

For ,elearning/the' can 'and operating-the seeming VAmeans the followin construction hasbeen devised; Worin-sha t dis provided withla worin d3, engaging`a wor1n-whee1 h of a cam-shaft h.l @This shaft isprovidedwith a n cam h? for. operating the clutch and brake in vers; but as their operating means are a ke the same description r.will apply to both. Each cani 71.3 is engaged-.by ahem-roller if, journaled in a laterally-extending. arniffof'a sleeve i3. The latter is vertically slidable upon a spindle i, mounted in bearings A3 A" and vertically adjustable by means of setscrews ifi S indie/,1 5I serves as a pivot for an upper or gui e lever and a loweror seamlever 7c, such levers havingttherefore coincdent tulcrurns. Guidelever j is provided with a tubular hub j', secu-red i spindle i. by a pin 52; The lowerthreaded end j of hui carries a nut j. To the free end of lever j is journaled a guide-roller 7'5", which travels in a groove l .of a cam-disk l, fast on shaft b. The groove l corres ends in form to that of the can to be headed. The lower section of ldisk l? constitutes a chuck Z2, which is .ad apted to enter the recessed cove-T BZ of can B, Fig. 9, and thus hold the can in position during the searning operation. The free or front end of 'lever k carries thel scanning-miler K, While its rear end is rovidcd with a tubular hub k',- which loosey surrounds hub j of lever' Huh 7c', and conse uently lever k, is held against vertical disp `acernent by hein com ined between lever j and nut. jt Hu kf is rovided with an outer longitudinal groove 2, engaged by a v'er`'cally1n vs.thle wedge kt. The latter is edgms'ahiy secured by .manner hereinafter'described andwith a Y of cams ha hsior operating -theseaminb-l'ei' vers. The drawings'shoiv two seeming-.le-

screws lc* to a slide 7c5, also en aging groove k2 and confined to the .same gby a cover k6. Slide k is provided at its lower end with a roller 7c', 'supported upon varm i. Thus slide c5 and Wedge ks will participate in the vertit cal reciprocat' movement imparted to arm 'i2 by cam h. l edge k3 bears a .ainst a roller m', journaled in lthe rear end o an auxiliary n `ver m, influenced by a s ring m2 and turnio ing onafulcruinnof guid-cever y'. The front end of lever m is b a pivoted link o connected to the seamingover lc. y

In order to permit a proper adjustment of roller K, fulcrum n is made in the form-of a x5 screw Whichis adjustably secured to lever by tapping` it' eccentrically in a cylindrica p u n. his plug is receivedlby a ilair of er orated lugs js, projecting laterally from ever y. Intermediate the ilugs j vplu 'It' is zo embraced by a ri "n, ca screwolt fn? and nut n4. Bylllosening ,said nut plug n is -v free to be turned, so as to adjust the position of plug a', and consequently of screw n. Af-

ter the adjustment has beeneiected nut n* is 5 again tightened.

By the construction described roller j5by engaging groove l swings the free end of lever y', as well ,as of lever k, toa'ssume a'position correspondin'gto the contour 'of the canbody. In addition to the movement thus imparted to lever' lathe latter V,receives by' Y wed e k3 a further inward movement, whereby t e selming-roller K is pressed against the can-,body to perform the sea 0 operation.

3 5 Wedge k is'operated in the fo owing manner: The rotation of cam. 71,a will cause a ver` tical reciprocating movement of sleeve 'i3 and it's arm z2. When said arm is raised, it

lift roller k and wedge k3. Wedge k3 ris- 40 ving will crowd roller m and consequently the rear end of lever m, awsy from spindle i., so as to press th'e seamin -ro er K against the canbo y and cause t e latter tofperform the seamin operation. When arm z2 is lowered,

wedge descends by avity to permit sprin m to swi 0* roller off the can-body B. he cams 7L .3 are so set that the rollers K K are consecutivelybrought into engagey ment with the can to be headed.' In t iis 5o way the first roller sfarts the seaming operation, while the sepond roller completes the saine, as usual.

Hand-lever g, hich serves to raise platform j", also serv s to start the nachine and to open the brake in the following manner:

Lever g is pro ded with a depending arm g5,

to which is oted oneend of a rd p, the

other end of which is connected to a lever r',

fast on a rock-shaft 1, which is journaled in 6a frame A. To rock-shaft 1* is secured an elbow-lever r2, the lower arm of Awhich is provided with a roller 13, engaging cam h2 of shaft h. The u :per arm of lever 1' is by rod s connected to a double lever t, pivotcd at t to frame A. This lever engages .a groove b3 of the movable member b4 of'clutch b bi, which may be of anyshitable construction. The drawings show a friction-clutch provided with radially-movable jaws b5. 'l'hese jaws are ressed against the inner surface of pulley li by eccentrics b and levers b7 bs when clutch member b4 is lowered. Lever t -is by rod u further vconnected to a brake-lever e, pivoted at 'v' to frame A and influenced by a spring if. Lever v engages the brake-shoe fw of a brake-disk w, fast on shaft l). It will 'be seen that by `depressing hand-lever g roller 1'3 will be lifted out of notch h* of cam h2. Further, the clutch member b* will be lowered to close clutch b'ln, and thus start the machine, while the brake w w is simultaneously opened by the engagement of stud o of lever i; with the tailpiece w of brake-shoe w. When the machine is started, roller r3 will ride along the convex edge h5 of cam h2, and thus prevent the clutch from openi Y, even after hand-lever g has been releasrd. After cam-shaft h has made a complete rotation rollerrs will enter recess h4 by the combined action -of the springs g @2f In this way lever r2 will tilt levers g, t, and fv to lower platform j" and open clutch b b* and also to set the brake.

It will be seen that in my improved machine the guide-levers and seeming-levers turn on coincident pivots and that the seaming-levers' are further influenced byj a vertica lymvable wedge in such a manner that the seeming-rollers are forced against the canin a simple and eilicient m anner.
